REFILL BOOK.

Application led February 8, 1923.

Books are in use for memoranda, checks, diaries, etc., in which theleaves are bound together in a package which is removable from the coverand replaceable by afresh package commonly called a refill. The cover ismade of expensive material so that it may be refilled a number of times,and the refill package is usually provided with end sheets ywhich may belabeled for filing away.

My invention provides certain improvements particularly designed for usein such refill books.

The accompanying drawings illustrate embodiments of the invention.

Referring first to Figs. 1 to 4, the leaves 1 are provided withrectangular slots 2 near their binding edges and fairly close togetheralong the lengths of such edges so that when bound by rings passingthrough the slots, the rings will eectively hold the sheets inalignment. In books of small capacity the leaves are necessarilyperforated extremely close to the-edge, and a multiplicity of fasteningpoints is essential in order to prevent accidental tearing out of theleaves.

These leaves are mounted on a binder, Fig. 3, consisting of a back plate3 which is curved backward at the edges and which at one edge is slittedand is provided with projecting tongues which are bent upward to formrings 4 of rectangular cross-section designed to fit properly in theslots 2 of the Serial No. 617,680.

leaves; the free ends of the rings 4 being carried around to practicallyor approximately contact with the top of the curved plate 3 at pointsslightly within the edge thereof.

. Such a binder is economically stamped up from sheet metal, the blankconsisting of a straight back with lateral projections (for the rings)so that t-wo such pieces can be blanked out of the sheet with theirlateral projections overlapping and with very little waste of metal. Thebackward curvature ofthe bar 3 means a reduction in its actual width andgives it an increased stiffness. In width, in fact, I prefer to make itapproximately equal to the outside diameter of the rings 4 or evenslightly less than this diameter, so that it could be held in the coverby a comparatively narrow fastening means, thus producing a very compactbook. Also the bending of the edges of the plate or bar 3 backward whilethe ring 4 bends sharply upward vat. its two ends, gives a wide V-shapedspace 5 and considerable freedom for insertion in the fastening means'Ihe fastening means comprises a plate 6 fastened between 'the twohalves of the cover 7 by means of a plate 8 on the back with prongs 9projecting up -through the leather of the back and through notches 10 inthe ends of the plate 6 and bent down on the top face of the latter. Thefastening plate 6 has inward flanges 11 along its side edges adapted toenter the triangular spaces 5 of the binder and to hold the latter inposition in the book. Various other fastening means for the binder maybe used. Likewise the fastening means or plate 6 may be attached to theback by the clinched tongues 9 or in various Iother ways, some of whichare described hereinafter.

',lhe anges 11 of the fastening plate are rounded or tapered on theirends to facilitate entry of the binder. The back plate 6 of the binderis tapered at one, end forthe same purpose. At its opposite end it isbroadened as at 3,'Fig. 3, or bent as at 3b, Fig. 5, so as tofrictionally engage the fastening plate and prevent accidental escape ofthe refill pad.

This method of fastening permits the use also advantageous in permittinga considerable tolerance in the width of said plate in manufacture. Thusplate 3 may be of less width than the space which it occupies in theplate 6, so that variations of width occurring in the manufact-ure willnot interfere with the interchangeability of theJ refills.

. When the refill is in place the method of binding the leaves withrings allows them to lie flat against either side of the cover. Forsmall books, therefore, this permits the use of practically everyportion of the leaves, whereas the ordinary refills are bound togetherso tightly at the ,edges that a considerable part of each leaf isuseless, particularly the leaves at the center. Vith the presentconstruction also when a leaf is torn out it can easily be taken outentirely with out leaving the torn stub which is commonly left inordinary bindings.

Figs. 6 and 7 show a construction which differs in several details.

The binder in this case comprises a plate 12 curved in cross-section, asshown, and with rings 13 which are separately made and then fastened onthe back plate 12 by springing the ends of the rings into notches in theplate in a manner well known in this art.

The fastening device for the binder 'consists of a plate 14 on the backof the cover 7 curved in cross-section and having on its lside edgestongues 15 which project at intervals through the back of the cover andform an interrupted holding and guiding means engaging the edges of thebinder, similarly to the ianges 11 of Fig. 4. In this case also thebinder plate 12is slightly bent in longitudinal section (as in theconstruction of Fig. 5) in order to hold the binder and its leaves witha frictional grip in the cover.

Fig. 8 illustrates the use of a cover consistlng of an outer ply 16 ofleathery anu' an. .inner'ply 17 of cloth and shows a fastening plate 18arranged between the two so as not lto show on the Voutside of the book.This plate 18 is similar to the plate 14 of Fig. 7 and has inwardlyprojecting flanges or tongues 19 serving to fasten the binder in thecover.

According to Fig. 10, the binder is formed o f a bottom plate 20, convexon the underside, a top plate 21, convex upward and rings 22 fastened inany usual or suitable way. In the bottom plate 20 there is a key holeshaped slot 23, Fig. 11, the larger part of which is adapted to receivethe head of a button 24, and the narrow part of which receives the shankof the same button. This button projects up from a'plate 25 fastened onthe back of the cover. When the refill is to be inserted inthe cover thekey hole is passed over the head of the button and the rell then sho-vedup into place,l

the parts being designed so that the plate 2O is gripped between thehead of the button and the back portion of the cover.

The sheets 7a shown in Fig. 10 are the filing sheets which form a sortof covers for the pad when the latter is withdrawn from the book cover.These filing sheets may be made 0f eXtra heavy or otherwise specialpaper and fastened between the plates 20 and 21 which in this caseconstitute the back of the binder for the leaves. The parts 20 and 21are fastened together by any usual or suitable means such as tongues 26bent up from the en'd of one of these plates and over notches in the endof the other.

After the sheets have been strung onto the rings and the latter bent topress their free ends down against the back plate, there may still be achance of the edges of the bottom sheet catching on the ends of therings. But with the arrangement described and illustrated, particularlyin Fig. 4, the flange of the fastening plate 6 which overlies thecorresponding edge of the binder plate 5 shields the free ends of therings from the sheets. v -z j To accommodate the extra width of therings thecover may be provided with slots 26, Figs. 2 and 9 through orinto which the rings extend when the book is closed.

Various other designs of the binder, cover and fastening means may beused, there 'being a great variety of suitable devices rnown to the art.For example, the slots in the leaves, instead of being closed slots asshown which necessitate tearing of the leaves in order to get them outseparately, may be key-shaped slots which by careful manipulation permittheremoval of a leaf without tearing it, and which indeed might permitthe introduction of new leaves separately, though the latter is not afunction of importance in refill books. The binder is for all practicalpurposes designed to permanently bind the leaves together in a pad.

It is this fact which permits the use of a multiplicity, that is threeor more, rings, as close together as may be desirable along the inner eges of lthe leaves. This fact also facilitates the binding of the leavestogether in a pad, no such operation being required as is called forwhere openings are to be left in the ringsfor the withdrawal orinsertion of sheets.

-Though I have described with great particularity of detail certainembodiments of my invention yet it is not to be understood therefromthat the invention is restricted to the particular embodimentsdisclosed. Va-
